Former senator Scott Brown has opened a state political action committee in New Hampshire, a move bound to stir further speculation that the Massachusetts Republican is interested in running for office in the Granite State.

Brown, who has been making frequent visits to speak to GOP activists in New Hampshire, registered the People’s Seat PAC Inc. with the New Hampshire secretary of state’s office this month.

Brown did not respond to messages seeking comment on Monday, but the PAC will allow him to donate to candidates for running for state offices in New Hampshire. Such donations can help a politician build a base of support in a new state. Brown already has a federal PAC with money left over from his failed Senate race.

Brown, who lost to Democrat Elizabeth Warren in Massachusetts last year, has drawn the attention of New Hampshire political leaders by refusing to rule out a run against Senator Jeanne Shaheen in 2014.

At a GOP fund-raiser in New Hampshire this month, Brown demurred when asked when he plans to make a decision about his political future.

“I’m doing exactly what I said I was going to do,” he said, “which is traveling around the country helping other committees, individuals, and groups raise money and raise awareness and try to get my message of problem solving.”

Brown has brushed aside critics who say he would be a long-shot candidate in a new state. He frequently points out that he owns a home in New Hampshire and says his family’s roots in the state stretch back nine generations.

Since losing his seat in Massachusetts, Brown has broadened his private-sector resume as well.

He is a lawyer at Nixon Peabody, a commentator on Fox News, and serves on the boards of Kadant Inc., a Massachusetts company that provides products and services to the paper industry; and Global Digital Solutions Inc., a Florida firm involved in manufacturing guns and gathering foreign intelligence for corporate clients.
